member adapted to be clamped down upon portions of the material or garment, and a rod for each angle member swivelly mounted to move laterally towards the angle member and arranged to provide the additional stretch required.

Still further the invention contemplates the use of a novel bolt for locking each pair of angle members and its associated rod in an operative position.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a plan view of a Shifili embroidery machine frame constructed according to this invention.

Fig. 2 is a perspective view of Fig. 1.

Fig. 3 is a fragmentary enlarged vertical sectional view taken on the line 3-3 of Fig. 1.

Fig. 5 is a fragmentary sectional view taken on the line 55 of Fig. 1.

. Fig. 6 is a view similar to Fig. 5 but illustrating the parts thereof in a different position.

Fig. '7 is a fragmentary perspective view of a portion of Fig. 1 looking in the direction of the line l-l thereof.

Fig. 8 is another view similar to Fig. 5 but illustrating separate garments clamped in the device.

The framefor Shifili embroidery machines, according to this invention, includes a pair of spaced parallel side arms Ill and II, and a plurality of parallel spaced bars l2 mounted between said arms and each bar being of curved, channel shape (see Figs. 5 and 6) in transverse cross section with one of the sides l2 of the channel shape narrower than the other side and this narrower side being provided with an outwardly extending flange 12*. An angle member I3 is provided for each bar I2 and is hingedly mounted at one of its ends by a bolt I4 upon the said bar I2 and is movable to have one of its sides, the side l3 (see Figs. 5 and 6) engage in the channel shape of the bar l2 and the other of its sides, namely the side 13', to extend over the flange IF. A rod I5 is provided for each of the flanges I2 and said rod is pivotally mounted thereon by a pintle rivet l6, and is arranged to be movable to a position between the flange and the adjacent side I3 of the angle member. This rod I5. is preferably curved and elastic, and made of tempered steel.

The side arm I0 is an angle member. The side arm II also is an angle member, and theseangle members have their rear legs in a common plane with their other legs remote from each other and extending in the same direction. The bars l2 are secured to the adjacent legs of the side arms l0 and H by several rivets ll so that the side arms and the bars I2are connected together as a rigid unit. v

The pivoted end of each angle member [3 has a cutout area l3? immediately adjacent the pivot end thereof. This area is cutout from one of the legs of the angle member so that the other leg of the angle member (see Fig. 4) is free, see the portion l3' It it through this portion l3 that the pintle rivet I4 is mounted. This pintle rivet l4 also engages through the wide arm of the channel shaped bar l2. The pintlerivet Eli engages through. the rod I5, then passes through the flange I2 then passes through a spacer tube l9, and then through the material of the side arm l0. A friction element, such as a tube of felt material or similar material 28, is mounted upon each of the rods l5 preferably at an intermediate area. This tube 20 extends from a short distance from one end of the rod to a short distance of the other end of the rod, in this respect see Fig. 2.

Each angle member [3 and rod I5 is provided with a locking bolt of novel design. There is a loop element 2| secured by several rivets 22 to one of the legs of the side member H. A bolt 23 slidably engages through the loop 2|. This bolt has a handle portion 23 by which it may be turned and moved longitudinally. The other end of the bolt 23 is provided with a hook portion 23 The bolt 23 is adapted to be moved over one leg of the angle member l3 to lock the angle member in position. This end of the angle member I3 is cutout at Hi to clear the adjacent edge of the leg of the side member H. After the rod I5 is moved laterally into position between the angle member l3 and the flange l2 the bolt 23 may be turned to move the hook end 23 across the edge of the rod IE to lock this rod in position. Several spring clamps 25 are mounted upon the side arm l0 and are adapted to support sheet material 26 to be embroidered. This material may be in the form of a garment, or piece goods, or a sheet of fabric of any size and material.

The operation of the device is as follows:

First the bars i 5 are swung to their open positions which comprise laterally extended positions, one such position being indicated by dot and dash lines in Fig. 2. Then the angle members I3 are swung upwards to their open positions. The cloth material or garment 26 is engaged by the clamps 25 to support one of its sides. The other side of the cloth material is pulled to make it taut and the first angle member I3 is pivoted downwards to force an area of the cloth material or garment into the channel shaped bar l2, and clamp it in position, as shown in Figs. 5 and 8. Then the cloth or garment is pulled taut laterally and the next angle member I3 is pivoted down to stretch the area between the angle members as shown in Fig. 5. In this manner each of the angle members it are moved down to their clamping position. These angle members are held in their clamping positions by the bolts 23 which are pushed laterally across the top sides of the angle members. The excess portion of the cloth or garment hangs down on the right hand side of the clamps.

A close inspection of Fig. 5 will show that the rods l5 are in inoperative positions with the web of the material above them, disposed at an in clination. The rods F5 are then pivoted laterally from the positions indicated in Fig. 5, to the positions shown in Fig. 6. This will force the webs of material off the flanges I2 since the rods engage into these areas. This causes extra stretching of the cloth webs or garment. In this manner the necessary additional tension is obtained in a very simple manner and both ends of garment remain on one side as shown on Fig, 8. The rods l5 are held in their operative positions by turning the bolts 23 so that the hook ends 23* engage over the edges of the rods l5 holding them in looking positions.

It is to be understood that the excess parts may also be made to hang on the left hand side of the clamping device, by making the clamping arrangement swingable toward the left, instead of the right direction.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
